Oscillations( Section A)
A1.
The phase of a particle in S.H.M. is π/2, then :
Restoring force on it will be minimum. Its displacement will be maximum.
A2.
At mean position,kinetic energy will be maximum and potential energy will be minimum
A3.
A simple pendulum whose period is two seconds is called a second's pendulum.
A4.
The epoch in simple harmonic motion (SHM) is the phase of a vibrating particle at the start of its motion, or when time t = 0. It's also known as the initial phase.
A5.
The time period of a (SHM) remains the same if its amplitude is doubled. This is because the period of an SHM depends on inertia and spring factors, which are independent of amplitude.
A5.
Force constant is the force required to produce a unit extension or compression in a spring. It's also known as the spring constant and is represented by the symbol k. The SI unit for force constant is newtons per meter (N/m).
A6.

A7.
given V = 0.24 m/s , a = 0.48 m/s2 to find time period T
formula : T = 2*pi*V /a
T = 2*3.14*0.24 /0.48 = 3.14 seconds
Time period T = 3.14 seconds
A8.
given T = 1/8 seconds , to find frequency F
formula : F = 1/T
F = 1/1/8 = 8 hertz
